I don't know enough about the "template users" thing to know how hard
it is to do; I do know that BSD/OS had a perfectly workable solution to
the problem of handling many thousands of name/password combinations which
ran in the same environment.

Fine, so we eventually need to have it.

Great. So?

By this argument, we ought to support Win32 executables natively, and provide
a system call for any program that wants setuid privs to be able to get them.
Ubiquity alone doesn't make a feature acceptable for NetBSD.

Great, so we include it.

My guess is that, were someone to provide a "login_pam", 90% of the things
for which PAM is used today would work without much effort. I'll see if
I can hit up one of the BSD Auth experts for some advice on how he'd solve
the AFS problems and similar ones; there may be obvious solutions to these
which I just haven't seen yet.
